BERNARD O. UlVII-IAU, OF WASHINGTON, DISTRICT OF COLUMBIA.

LUBRICATOB FOR ELEVATOR-GUIDES.

' Washington, in the District of Columbia,

have invented a new and useful Lubricator for Elevator-Guides; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a new and useful lubricator adapted to be carried by an elevator and provided with means for partially embracing the guide track of the elevator, so as to lubricate the same.

The invention in its broadest scope aims as its primary object to provide a practical, simple and efficient lubricator having a frame, for the support of a globular oil cup or receptacle and fabric feeding wicks leading from the cup and supported by an adjustable frame (consisting of two parts), for supplying the gravitating or compression members with oil or grease. These gravitating or compression members are designed to engage the faces of the guide rail or track of the elevator shaft. The object in providing the adjustable two-part frame is to increase or decrease the space between the gravitating or compression members, so as to accommodate guide rails or tracks of different thicknesses.

A further object of the invention is to provide metallic means clamped in the fabric wicks of the gravitating compression members, in order to engage the surfaces of the guide track or rail, thus obviat-ing the possibility of the extremities of the wicks becoming quickly and considerably worn.

In the drawings, however, there is only disclosed one form of the invention, but, in practical fields, this form may require alterations, to which the applicant is entitled, provided the alterations are comprehended by the appended claims.

The invention comprises further features and combinations of parts hereinafter set forth, shown in the drawings and claimed.

In the drawings z-Figure 1 is a view in elevation, showing the application of the lubricator upon an elevator car, and constructed in accordance with the invention. Fig. 2 is a top plan view of the lubricator,

showing the extreme top plate of the frame thereof removed. Fig. 3 is a sectional view on line 3 3 of Fig. 2. Fig. 4 is a sectional Speccation of Letters Patent.

view on line 4 4 of Fig. 2. Fig. 5 is a detail perspective view of one of the members, for holding and suspending the wicks. Fig. 6 is an enlarged detail sectional view transversely through one of the gravitating compression members. Fig. 7 is a view of one of the gravitating or compression members, showing the parts thereof disassembled. Fig. 8 is a sectional view on line 8-8 of Fig. 3.

Referring to the drawings, l denotes the elevator car or cage,rwhich is provided with an arm 2, while 3 designates the arms of the Ushaped member 4, which is secured by bolts and nuts 5 to the frame 6 of the lubricator. The frame 6 consists of three plates 7, 8 and 9. The plates 7 and 8 are considerably spaced apart by the standards 10, through which the screwlbolts l1 penetrate. The plate 9, however, is arranged immediately above the plate 8, and held separated from the plate 8 by the nuts 12, which are threaded upon the screw bolts l1. The plate 9 is secured in place by the nuts I3 which also are threaded to thescrew bolts. Removably arranged between the plates 7 and 8 is the globular grease or oil cup or receptacle 14, which is held from displacement laterally in three directions by the standards 10. However, the grease cup is held from displacement in a fourth direction by the head of the split pin 15, which extends through the plate 8.

To secure the U-shaped member 4 to the arm 2, a thumb bolt 16 is provided, which is threaded through one of the arms 3. The arms 3 engage upon each side of the guide rail 0r track 0f the elevator shaft, thus constituting means for guiding the lubricator device relatively with regard to the track.

The plate 8 is provided with a shouldered portion 17. Wick holders 19 are provided which are constructed of sheet brass or any other suitable material. These holders are slightly elliptical in cross section and are designed to receive the end portions of the U-shaped wick 20, the loop 2l of this wick resting upon the top of the plate 8, and is of suiiicient width to permit of adjustment of the holders. ATo adjust the holders, the same are provided with extensions 22, which are supplied with down-turned flanges 23, which engage the shouldered portion 17, thus constituting guiding means for the holders. To hold the down-turned flanges of the eXtensions adjacent the shouldered portion 17,

washers 23a are provided, through which the screw bolts 24 extend so as to hold them in place, there being nuts 25 threaded upon the screw bolts 24. The U-shaped wick 2O feeds the lubricant or grease to the wicks 26, which are secured in the holders by the split pins 27. Suspended at the lower ends of the wicks 26 are the gravitating members 28. These gravitating members 28 are designed to distribute the grease or lubricant proportionately upon the faces of the guide track or rail of the elevator shaft.

A central wick 29 is secured to the shouldered portion 17 of the plate 8, with its end 30 extended through a slot of the plate 8 and arranged in the globular grease or oil cup. A split pin 3l is utilized for securing the central wick in place. A gravitating member 32, like the gravitating members 28, is suspended from the central wick, and disposed adjacent the outer face of the guide railor track of the elevator shaft. Thus it will be observed that by virtue of the gravi! tating members 28 and 32, three faces of each guide rail or track are thoroughly Vgreased or lubricated.

The gravitating or compression members 28 and 32 are similarly constructed, namely, they comprise the bent plates 33, between which the extremities of the wicks 2O and 29 and extra pieces of wick material 34 are clamped. Also clamped in between the plates and in the wick material are metallic members 35, thus constituting means for obviating to a great extent the wear upon the wick material. The plates 33 are provided with lugs 36 adapted to be inserted through the apertures 37 of the fiber disks 38, and afterward clenched or bent in opposite directions, as shown in the drawings. These fiber disks constitute flanges or means, between which the rail or guide track of the elevator shaft passes.

The wick 29 rests upon the loop of the wick 20, so that as the grease or oil feeds up the wick 29, it is transferred therefrom to the wick 20. The grease or lubricantfeeds along the ends of the U-shaped wick 20 to the wicks 26, and down to their extremities, beyond the plates 33, from which it is supplied upon the faces of the guide rails or tracks of the elevator shaft.

The gravitating members 28 not only constitute means for holding the wicks adj aeent the guide rails or tracks of the elevator shaft, but also constitute means for retarding the feed of the lubricant through the wick. For instance, when constructing the gravitating members, the wicks 26 and the extra pieces of wick material 34 when placed together are substantially twice as thick as the diameter of the apertures 37, thus necessitating suiiicient pressure upon the plates 33, so as to compact the wicks and the extra pieces 34 closely together, so that the lugs 36 will pass through the apertures 37. By compressing the wicks 26 and the extra pieces of material 34 together the lubricant containing cells of the fabric will be considerably closed, thus retarding the lubricant as it feeds.

The invention having been set forth, what is claimed as new and useful is l. In combination, a frame adapted to be secured to an arm of an elevator cage, a pair of wick holders carried by the frame including feeding wicks, means for permitting two of the wick holders to be adjusted toward and away from one another', and means constituting compression devices suspended from the free ends of the wicks to retard the lubricant.
